Anker Nano Pro 511 A2637 20W Charging Adapter

The Anker Nano 511 (Model A2637) is a super-compact, high-efficiency USB‑C wall adapter that packs 20 W of power into a tiny 1.16 × 1.16 × 1.18 inch frame. Thanks to its GaN (Gallium Nitride) technology, it stays cool and efficient despite its high power density, making fast charging quick and safe. It supports two main output levels — 5V ⎓ 3A and 9V ⎓ 2.22A — allowing it to deliver optimized charging for a wide variety of devices, especially fast-charging iPhones. Anker integrates its ActiveShield™ safety system in this charger: a dynamic temperature sensor actively monitors heat, and a power‑tuner chip adjusts output to keep things safe. Weighing around 50 g, it's lightweight and travel-friendly. It also supports a broad input voltage range of 100–240V, making it usable globally for travel. Despite its compact size, it's powerful and safe enough for daily fast charging.
